"Reimagining the Road Ahead" delves into the concept of car-free days, especially their implementation in Bogotá and Paris, the political and practical challenges to their widespread adoption, and the broader push to re-imagine urban spaces with fewer cars.






Interviews:Enrique Peñalosa is a Colombian politician and urban strategist who served as mayor ofBogotá (1998–2000, 2016–2019). He is known for championing sustainable urban mobility,including Bogotá’s TransMilenio bus system and the city’s first Día Sin Carro (Car-Free Day), abold initiative that reshaped public attitudes toward transportation and urban space. His policiesprioritized pedestrian and cycling infrastructure, aiming to create a more equitable andaccessible city.https://en.wikipedia.org/wiki/Enrique_Pe%C3%B1alosa
